I don't think promiscuity and low self esteem are always connected. Women can be very sexually confident and enjoy sex with different partners. However, I think, the majority of the time, it is because of low self-esteem.

Still, it bothers me that society puts down promiscuous women, especially since they do so without treating men the same. I don't judge my friends based on if they have lots of sex with lots of people; I might express concern for them, but I won't avoid them or think they're a "skank" or a "ho." I just let them know, if they're ok, it's fine, and if they want someone to talk to, I'm here. As long as they're not sleeping with my guy, I'm ok with it.

There are good guys out there who don't treat women like crap. You just need to find one. It's not always easy, but it can happen.
